1. To prepare the potatoes, scrub them clean if dirty and rinse under running water. Remove and discard any sprouting areas. Place the potatoes in a large pan.
2. Fill the pan with water until the potatoes are submerged and covered by 1 inch of additional water. Add a pinch of salt. Bring the mixture to a boil over medium-high heat and continue cooking until the potatoes are very easily pierced through by a fork (smaller potatoes are done around 20 minutes, and medium around 25 minutes).

3. While the potatoes cook, preheat the oven to 220°c and drizzle 1 tablespoon of the olive oil over a large, rimmed baking sheet/ roasting dish. Brush the oil so it’s evenly distributed over the sheet.

4. When the potatoes are done, drain them in a large colander and let them cool for about 5 minutes, until they can be handled safely.
5. Evenly distribute the potatoes over the prepared baking sheet, and use a potato masher or a serving fork to gently smash each potato to a height of about ½ inch. (Thinner potatoes are more crispy.)
6. Drizzle the remaining 3 tablespoons of olive oil over the smashed potatoes. Sprinkle the garlic powder, onion powder and remaining ¼ teaspoon salt over the potatoes. Finally, sprinkle them lightly with freshly ground black pepper.
7. Bake until the potatoes are nice and golden on the edges, about 25 to 30 minutes.

Serve and enjoy!
